Some 4,000 Palestinians bid farewell to martyr Motazz Washaha who was killed a day earlier by Israeli occupation forces in West Bank.

Washaha was martyred during a raid for occupation forces to his home in the town of Birzeit, north of the West Bank administrative center of Ramallah.

The martyr was a member of the leftist Popular Front for the Liberation of Palestine, and the movement's flags were visible at the funeral.

Mourners at the massive funeral called on Palestinian factions to unite and avenge Washaha's killing.

Earlier, Amnesty International slammed the Zionist entity for killing of dozens of Palestinian civilians in the occupied West Bank over the past three years.

"In some [cases], there is evidence that they were victims of wilful killings, which would amount to war crimes," a report for the non-governmental organization (NGO) said.

It "shows a harrowing pattern of unlawful killings and unwarranted injuries of Palestinian civilians by Israeli forces in the West Bank," said Philip Luther, director of the Middle East and North Africa Program at the NGO.

"Without pressure from the international community, the situation is unlikely to change any time soon," he continued.
